Application filed November To all tau-710m it. may concern:

Be it lrnown that 1, Jose F ERRY GARCIA, a sub ectof the King of Spain,and resident 'of Hzrbana, Cuba, have invented certain new and usefulImprovements in Plowing Machines, of which the following is aspecification.

This invention relates to plowing machines, and its object is to providean improved machine of this class embodying an improved share which isarranged for rotation and operates somewhatlike an anger in plowing andloosening the soil.

Another object v of this invention is to combine in a machine aplurality of said earth working plows or shares, and to provide meansfor regulating the depth at which they operate inthe soil.

Another obj ect of the invention is to provide means for raising theplows and holding them in raised position where desired.

A further object of theinvention is to provide gear mechanisms fortransmitting motion from the motor shaft on a driving vehicle to saidrevolving plows mounted on the same vehicle.

The invention; is described with reference to the figures of the annexeddrawings, in which: I

1 is a side elevation of .a plowing machine constructed in accordancewith this invention. I

2 is a top plan view of the same.

Fig. 3 is a longitudinal vertical section, on line 3-3 of Fig. 2.

Fig. t is a partial longitudinal vertical section, on line 4-4 of Fig.2.

Fig. 5 ;is a cross vertical section, on line 5-5 of Fig. 2. I

Figt ti i's a cross vertical section, on line 66 of Fig. 2.

nersides of the holsters of chassis l and are raised above the sameowing to the fact that the axle-boxes 8 of frame 7 are below the sidesof said frame (Fig. The sides of frame 7 terminate at their front endsin smooth vertical sectors 9 connected together by a pair of cross bars10. Said sectors are concentric with and on one side of thecorresponding sectors 11, which rise from a cross plate 12, and aresecured attheir bases by wings 12 and screws 13 to the inner faces ofthe holsters of chassis 1. The stationary sectors 11 are connectedtogether-by a transverse plate- 14. secured with screws. The stationarysectors 11 have at their inner arcuate edges rack teeth 15 for meshingwith gear pinions 16 which are secured on the ends of a horizontal shaft17 mounted on bearings 18 arranged on the upper ends of the movingsectors 9. Motion is transmitted manually to shaft 17 by means of acrank, 19 fixed on the end of a short horizontal shaft- 20 mounted onbrackets 21 connected to brackets 22 which are fixed on one of the crossbars 10. Said short shaft 20 carries a gear pinion 28 which meshes witha gear pinion 24L fixed on the center of the shaft 17'. The movingsectors 9 may be secured inan'y required position with respect 8 tostationary sectors 11 by means of a catch 25 Fig. 4) which passesthroughthe upper crossbar 10 and is arranged in a spring casing -26andladapted to be inserted in one of a the three or more openings of ablock 27 which is fixedfto cross plate 14. Said catch 25 is providedwith a smallhandle 28 by which it may be operated. I

The moving sectors 9 are reinforced by braces 29 which lead from upperextensions 7 projecting from the sides of the rocking frame 7 and fromsuch extensions 7' braces 30 extend rearward-1 and are connected tostandards 31 which are integrally connected to the rear parts of thesides of frame 7. Said standards re connected together b a cross bar"32. On bearings 33 fixed below the lower bases of extensions 34 which.pr0 jeot downwardly from the sidesof frame 7, at the rearjparlts of thesame, is rotatably mounted a loose horiZontalsha-ft 35 which acts as a"pivot t "a plurality of vertical frames separatel and .equidistantlydistributeii on said pivot 35 and supported on the latter and on anotherhorizontal shaft 37.1115: 1 a th'roughisaidframesf36 on bearings eachone closed at the sides'by a block 38 sliding on a slot 38' formed ineach frame 86. Each block is secured by a pair of screws 39. Said shaft37 has cranks 40 at its ends, and said shaft has gear pinions 11 whichmesh with gear sectors 12 formed at the rear end of each side of theframe 7 (Fig. 1). Inclined bars 43 project rearwardly and downwardlyfrom said sectors and have extensions 3 which extend below the pinionsl1. On the base of a recess .1. 1 formed on the rear upper part of eachframe 36 are secured two short standards l5 and 46 spaced apart and onwhich is mounted a longitudinal crank shaft 47. The cranks of thevarious shafts 4:7 are in the spaces between the said standards. All thecrank wrists 47 are connected together by bars 48 and 4,9 which aresecured together by bolts 50. The rear ends of crank shafts 47 areprovided with beveled gear pinions 51 which mesh with beveled pinions 52fixed on the upper ends of vertical shafts which are mounted in bearingpieces 54L secured by screw-bolts 55 to the rear part of each frame 36.On the lower ends of said vertical shafts 53 are secured beveled gearpinions 56 which mesh with beveled gear pinions 57'li2red on the rearends of substantially horizontal or slightly inclined shafts 58. Saidshafts 58 are mounted in bearing pieces 59 fired by bolt screws 60 tothe lower part of each frame 86, said shafts 58 forming stems which areintegral with the nucleus of shares or plows for working the soil. Saidplows at their front half portion are of helical form as at 61 and eachterminates in point 62. At the rear part the helix is widened and cut ina diamet-ral plane to form a mould board 62 the function whereof is toguide the ground raised through the. helical part 61 and to invert thesame.

Motion is transmitted to the various crank shafts 47 from the drivingshaft 6 1 by the cross shaft 65 which transmits power to the shaft 4: ofthe traction wheels 5-by means of sprocket wheels 66 and 67 and endlesschain 68. A second cross horizontal shaft 69 is mounted behind thetraction wheels 5 of the vehicle, in bearings 70 formed below thedownward extensions of the sides of frame 7. On the ends of said shaft69 are sprocket wheels 71 connected by endless chains 72 with sprocketwheels 73 fixed on shaft 4 of the vehicle. Shaft 66 has a beveled gearwheel 74 applied thereto and a beveled gear wheel 75 loose on sameshaft, which beveled gears 74 and 75 mesh with the diamet i allyopposite sections of a lower beveled gear crown of a large horizontalwheel 76 whose trunnions 77 are mounted on brackets 78 and "79 each ofwhich comprises four arms which are integrally connected to fourmountings 80 fixed to the sides of frame 7. Said crown 7 6 meshes at therear end of its longitudinal diameter with a beveled gear wheel 81 fixedon the front end of a longitudinal horizontal shaft 2 which is mountedin a bearing piece 83 i'xed by bolt screws 841 at the upper part of thecentral frame 36. Said shaft is integrally connected to the respectivecrank shaft 17. Frame 7 presents at the rear part a cross bar 85connecting the sides of said frame by means of upwardly directed wings86 which extend on both ends beyond those sides to act as an upward stopto frames 36. Said cross bar 85 has a central portion 87 of semicircularform for acting as guard to the beveled conical wheel 81.

On the rear part of frame 7 is securely arranged a seat 88 for theoperator of the plows 61. On the chassis 1 is securely fixed the usualseat 89 for the driver of the vehicle. On frame 7 'an be arranged anawning 90 supported by standards 91 and 95 3 properly secured on thesides of frame 7, and in like manner on chassis 1 there can be arrangeda section of awning 93 supported by standards 9 1 securely listed to therear part of engine 6.

The operation of this machine is as follows: Through the described gearmecha nisms, motion is transmitted from shaft 4; of the traction wheels5 and while the vehicle is in motion, to the plows or revoluble shares61, which, being slightly inclined, operate in an auger like manner,boring the ground as the machine travels, the earth going up through thespirals of the wider helix 63 and dropping down beyond to be inverted.When it is desired to change the depth at which the shares 61 are tooperate, catch 25 is pulled back to disconnect it from block 27, andcrank 19 of shaft 20 is turned in one direction or the other so thatshaft 20 may cause the rotation of shaft 17 carrying the gear pinions 16which run on the arched racks 15 of the stationary sectors 11, cans ingthe whole frame 7 to rock with the mechanisms supported thereon aroundthe hori zontal pivoting shaft 1. The shares or plows 61 are caused topenetrate more or less into the ground as may be required.

hen the operation of the plows 61 is to be suspended, that is, when themachine is to travel without working, the plows are raised by actuatingthe cranks 10 of shaft 37, which on causing the gear pinions 11 torotate, which by meshing with the gear sectors 42 cause the rockin ofthe frames 36 on the pivoting shaft 35 to be turned until the points 62of plows 61 come up fromthe ground. .Vhen it is desired to put the plowsin operation the proceeding is reversed.

It should be understood that the details of construction of themechanisms of support and of transmission of motion to therevolublepshares can be varied within the spirit of the invention, andwithin the scope of the appended claims.

'What I claim is 1. A plowing machine comprising a motor vehicle, arocking frame mounted on the rear axle of the vehicle, means forcontrolling the position of the rocking frame with respect to thechassis of the vehicle, a frame pivotally mounted on the rear part ofthe rocking frame, an earth working element rotatably mounted at thelower part of said last named frame and means to actuate such element,such actuating means being operative in only one position of the lastnamed frame but in any of the adjusted positions of the rocking frame.
